The ichthyo fauna of the middle course of the jihlava river in relation to the water reservoir at dalesice


, : The ichthyo fauna of the middle course of the jihlava river in relation to the water reservoir at dalesice. Folia Zoologica 26(3): 255-269

The fish community, abundance and biomass of particular species, and the angling pressure and fish exploitation were investigated in the Jihlava River, [Czechoslovakia]. Of the 25 spp., only the following formed more numerous populations: chub, barb, Chondrostoma nasus, gudgeon, roach and Alburnoides bipunctatus. The first 3 spp. made up a substantial part of the biomass and of the anglers' harvest. Two dammings at the village of Dalesice, supposed to be completed in 1977, resulted in formation of 2 water reservoirs. A large part of the investigated river course will be flooded. Profound changes of water temperature and water discharge are expected to occur in the remaining part of the stream below the future reservoirs. Proposals concerning the new fish stocks both for the water reservoirs themselves and for the river course below the dams were discussed.
